| Interaction |
Since acetylcholinesterase inhibitors can cause bradycardia and heart block due to vagotonic effects on the sinoatrial and atrioventricular nodes, additive effects may occur with other agents that also possess bradycardic effects such as beta-blockers, calcium channel blockers, digitalis, some protease inhibitors (atazanavir, lopinavir-ritonavir, saquinavir), amiodarone, dronedarone, moricizine, lacosamide, and mefloquine.

| Management | Caution is advised if acetylcholinesterase inhibitors are used concomitantly with bradycardic drugs. Patients with underlying structural heart disease, preexisting conduction system abnormalities, ischemic heart disease, or cardiomyopathies may be at increased risk for developing cardiac conduction disturbances and atrioventricular block. Patients should be advised to notify their physician if they experience dizziness, lightheadedness, fainting, or irregular heartbeat. |

Potential Metabolism Interactions
Substrate-Substrate Interaction：If more than one drug is metabolized by the same CYP, it is possible that its metabolism is inhibited because of the competition between the drugs. That means, it can be useful to lower the dosage of the drugs in the drug-cocktail because they remain longer in the organism than in monotherapy.
Inhibitor-Inhibitor Interaction：Combining two or more inhibitors of one CYP, should be compensated by lowering the dosage of these drugs because the metabolism is reduced and the drugs remain longer in the organism than in monotherapy. Not adapting the dosage bears the risk of even more side effects.
Inhibitor-Substrate Interaction：Combining drugs that have inhibitory effect and are substrates of one particular CYP, should be compensated by lowering the dosage. They rest longer in the organism than in monotherapy. Not adapting the dosage bears the risk of even more side effects.
